Mystery Pokemon GBA Games

So Santa informed me that he did a lot of digging to find these, and I am absolutely in love that I got not 1, but 2 Pokemon games! However, I do not own a GBA at the moment (working on getting one to try these games out), but I'm thinking its Pokemon Sapphire and Pokemon Ruby? Anyway of finding out without a label or a system?

Regardless, Santa thank you! You did a tremendous job of sending this over and I am grateful! This will go well with my gaming collection!
